Abstract (en)
[origin: EP3091380A1] An optical coupling arrangement (10) is provided, comprising a lightwave circuit, LC, (100), a coupling element (200) and an optical waveguide element (300), wherein the LC (100) has a first surface area (110) and wherein the coupling element (200) is attached to the first surface area (110) such that an optical signal can be transmitted from the LC (100) to the coupling element (200). The optical waveguide element (300) is attached to the coupling element (300) at a first junction zone (202) such that the optical signal can be transmitted from the coupling element (200) to the optical waveguide element (300). The coupling element (200) is configured to perform mode transformation to the optical signal transmitted from the LC (100) to the optical waveguide element (300) and such that adiabatic coupling of the optical signal to the optical waveguide element (300) is enabled. Thus, a better coupling efficiency can be achieved.
